Ag Braking

Over the last handful of years, members of AEM, the Farm Equipment Manufacturers Association (FEMA), and the Agricultural Manufacturers of Canada (AMC) have devoted countless hours within the American Society of Agricultural and Biological Engineers (ASABE) to bring the five-part ANSI/ASABE S648 Agricultural Field Equipment Braking Standards to where it is today. The standards made it through a total of four committee ballots before reaching the ASABE MS-03 oversight committee for the final process review for approval. ANSI (American National Standards Institute) has approved the five parts of the ANSI/ASABE S648 standard and publication is expected in late March of 2020.

Replacing ANSI/ASAE S365.9, the ANSI/ASABE S648 Standards define specific requirements, minimum performance criteria, and performance test procedures to accommodate the ever-changing design and capabilities of agricultural field equipment. One of the most notable changes in modern agricultural equipment that played a major role in the development of the standard from a safety perspective is the relationship between the increased speed capabilities and the overall mass of the tractors and towed equipment. While many are already adhering to these standards, it is important for the manufacturers to review their design and testing procedures to assure the industry as a whole is continually progressing with safety as a top priority. A snapshot of the five parts are listed below and the full version can be purchased through ASABE.

ANSI/ASABE S648 Agricultural Field Equipment Braking Standard

Part 1: General Requirements

  • Define terms and establish common requirements, minimum performance criteria and performance test procedures that are common to agricultural field equipment.

Part 2: Requirements for Agricultural Tractors

  • Establish specific requirements, minimum performance criteria and performance test procedures that are common to agricultural tractors when used in conjunction with ANSI/ASABE S648-1.

Part 3: Requirements for Self-Propelled and Special Self-Propelled Equipment

  • Establish specific requirements, minimum performance criteria and performance test procedures that are common to self-propelled and special self-propelled agricultural equipment when used in conjunction with ANSI/ASABE S648-1.

Part 4: Requirements for Towed Vehicles

  • Define the minimum stopping requirements related to braking of towed agricultural field equipment hereafter referred to as towed vehicles when used in conjunction with ANSI/ASABE S648-1.

Part 5: Requirements for the Interface Between Towing Vehicle and Towed Vehicles

  • When used in conjunction with ANSI/ASABE S648-1, defines the requirements for interfacing service and parking brake systems on towing vehicles with service and parking brake systems on towed vehicles.

Again, all of the effort put forth by the members of AEM, FEMA, AMC, and ASABE to take this project from start to finish is greatly appreciated and highly commendable.
